This control consists of permanent marks with precisely determined latitudes, longitudes and elevations. PACS and SACS are designated by the National Geodetic Survey and must meet the specific siting, construction, and accuracy requirements. PACS coordinates are established by meeting a survey, data processing, adjustment and reporting standard known as the NGS Bluebook. == See also == Airport security Aviation safety == External links == The NGS complete list of airports with PACS and SACS Input Formats and Specifications of the National Geodetic Survey Data Base PACS and SACS overview with diagrams == References == - [[Professional Practice/Codes & Standards/National Building Code of India/Part 03 - Development Control Rules]] - [[Professional Practice/Construction Management/Quality Control]] - [[Environmental Design/Building Climatology]] - [[Design/Building Typologies/Residential Architecture]] - [[History and Theory]] - [[History and Theory/World History/Classical Architecture]] - [[Environmental Design/Daylighting Design]] - [[History and Theory/World History/Ancient Architecture]] - [[Interior Architecture/Renovation and Conservation/Restoration Techniques]] - [[Structures/Structure Systems & Design]]
